DRAWBAR POCKET.

Application nieu August ai, 1922. serial No. assess.

To all whom t may concern;

Be it known that I, EDMUND S. Bnonn'rrn,

, a citizen of the United States, residing atv East St. Louis, Illinois, have invented a certain. new and useful Improvement in Drawbar Pockets, of which the following is a full, clear, and exact description, such as pwill enable others skilled in the art to which it appertains to make and use the same,ref erence being had to the accompanying draw-l ings, forming part of this application.

My invention relates to'l railroad rolling .iystockand consists in anV improved drawbar pocket especially adapted for use on the locomotive and tender ,where the coupling comprises linkswhich are duplicated to provide service and emergency couplings.

The objects of my invention are to pro#v vide a simple construction of the pockets, a maximum of strength in a minimum space and especially to reducev the verticalextension of the-pocketmember below the locomotive or tender frame.

On account of the application of booster engines to locomotives, it is necessary to have the drawbar pocket on rear end of engine as shallow as possible and still accommodate the upper service drawbar and lower emergency drawbar, pivoting about a common vertical center. I obtain this result by casting integral bosses in the drawbar pocket and providing them with metal bushings which can be replaced when worn.

In the accompanying drawings which illustrate a selected embodiment of my invention,

Figure 1 is a longitudinal section through the rear of the locomotive and the front of a tender equipped with my invention.

Figure 2 is a transverse Vertical section taken on the line 2-2 of Figure 1.

The pocket is applied to the rear end of the locomotive frame 1 with its open side extending rearwardly. The frame is here shown as a casting and the pocket illustrated as formed integral therewith, having the lower surface 2 of the frame for its upper wall, side walls 3 and 4, a rear wall 5, and a bottom wall 6. Integral with top wall 2 and bottom wall 6 are circular bosses 7 and 8, respectively, the former extending downwardly and the latter extending upwardly from the surrounding wall surface for a distance approximately the same as the thickness of the coupling links 9 and 10.

The distance between the horizontal planesy bounding the lower face of the boss 7 and the upper face of boss 8 is equal to or somewhat greater than the thickness of links 9 and 10. Renewable bushings 11 are placed upon bosses 7 and 8 and are preferably formed of harder material than the bosses.v These bushings are intended to receive the wear produced by sliding contact with the links and withstand same better than the bosses would,

besides having an additional advantage of being renewable. Y

The side walls 3 and 4f of the pocket are provided with openings 12 for the insertion and retaining of a removable transverse member 13 which is located between links 9 and 10 and prevents dropping of linky 9v or the rise of link 10 and therefore locks these links in boss engaging position. Mem.l

ber 13 is provided with cotters 14 at each end and is preferably beveled as indicated at 15 on one end to facilitate its insertion between links 9 and 10.

In applying the pocket to the tender frame, I have shown it as a separate casting secured to the frame by suitable bolts or rivets instead of being cast integrally with the tender frame. The essential features of the pocket and the securing of the links therein are retained however.

lhile I have illustrated both upper and lower bosses provided with hardened bushings, it is likely that in practice the lower boss, adapted to be engaged by the emergency coupler, will not be bushed as its service is more limited and the additional wearing element is unnecessary.

Suitable reinforcing ribs 16 are indicated on the castings and it will be understood 'that these may be altered or increased as desired and other modifications in the details of my invention may be provided without departing from the spirit of the invention as expressed in the following claims.

I claim:

1. In a drawbar pocket, an upper wall, a lower wall, opposed bosses on said walls each adapted to be engaged by a drawbar, and a removable member positioned between said bosses and of greater sectional area than said bosses to retain said drawbars in engagement with said bosses.

2. In a drawbar pocket, an upper wall, a lower wall, opposed bosses on said walls, each adapted to be engaged by a drawbar, and

f means forY maintaining engagement of said bosses by drawbars positioned in said pocket. P

pln` a drawbar pocket, an upper Wal-l, a lower wall, opposed "bosses in said walls, eachadapted to be engaged by a drawbar, and a removable member extending trans:-

. versely of the pocket between the ends of said bosses.

4. In a drawbar pocket, an upper wall, a

` lower wall, opposed bosses in said walls, each adapted' to be engaged by a drawbar,

adapted to be engaged by' respective draw bars, a removable member extending trans versely of the pocket between the ends of said bosses and through Vsaid side walls, and removable means insaid member for engagingu said side walls;

6; In combination, a drawbar pocket hav ing an interior, the height of which is approximately three times the thickness of the drawbar to be inserted therein, a boss pro- `jeeting upwardly from the bottom ofl the pocket approximately the 4distance of the thickness of a drawbar, and a similar boss proj eeting downwardly from' the top of the i and approximately as thick as the distance` between the opposed faces of said bosses.

7. In combination, a onepiece drawbar pocket casting having upwardly and downwardly projecting bosses in its interior, the opposing faces of said bosses beingv spaced apart, and replaceable bushingsof hardened materialinserted between said bosses and fitted over the same;

8. In a one-piece locomotive' frame, having a horizon-tal pocket extending inwardly from one end thereof, integral 'bosses onthe upper and lower walls of said pocket adaptedto en-, ,0 agel a drawbar link, the side Walls of said pocket being provided with openings' adapted to receive a removable transversev member' positioned intermediate the 'planes' of the ends of said bosses.

9; In combination, a oneieee draw-bar pocket casting having upwa-r ly and downwardly projecting bosses in itsl interior, the opposing fates of said bossesbeing spaced apart, and a replaceable bushing' of hardened material inserted between; said bosses andiitted over one of the latter.

In testimony whereof I hereunto ax my signature this 12th day' 'of August, 192.
